Question

Find the value of x


(A) x= 135
(B) x= 25
(C) x= 35
(D) x= 90

Answer 1

C) 35

Explanation:

The sum of the interior angles of a triangle is 180°. We also have a right angle which is 90°.

2x - 8 + 90 + x -7 = 180 Combine like terms

3x + 75 = 180 Subtract 75 from both sides

3x = 165 Divide both sides by 3

x = 35
